My X50 started making the KA "type" sound to the K band tonight. At first I thought Oh theres a leo around. Nope it was just the false K band signal at my work. It was the double chirp sound but higher pitch. I would have got it on video or taped it with the phone, but did not have either one of those recorders with me. I had wish I did.
It is cold out and the X50 was left in the car, but I have left it in the car w/ much colder conditions and it has never had a issue like this.
Maybe my X50's days are over and its saying, I'M TRYING GIVE ME A REST"
Which means if it does stop, look out new 9500 or V1, maybe even an STI.
